霍爾元件應(yīng)用霍爾效應(yīng)的半導(dǎo)體。所謂霍爾效應(yīng)，是指磁場作用于載流金屬導(dǎo)體、半導(dǎo)體中的載流子時，產(chǎn)生橫向電位差的物理現(xiàn)象。金屬的霍爾效應(yīng)是1879年被美國物理學(xué)家霍爾發(fā)現(xiàn)的。當(dāng)電流通過金屬箔片時，若在垂直于電流的方向施加磁場，則金屬箔片兩側(cè)面會出現(xiàn)橫向電位差。半導(dǎo)體中的霍爾效應(yīng)比金屬箔片中更為明顯，而鐵磁金屬在居里溫度以下將呈極強的霍爾效應(yīng)。利用霍爾效應(yīng)可以設(shè)計制成多種傳感器?；魻栯娢徊頤H的基本關(guān)系為：式中 RH――霍爾系數(shù)；n――單位體積內(nèi)載流子或自由電子的個數(shù)；q――電子電量；I――通過的電流；B――垂直于I的磁感應(yīng)強度；d――導(dǎo)體的厚度。對于半導(dǎo)體和鐵磁金屬，霍爾系數(shù)表達式和式（2）不同。由于通電導(dǎo)線周圍存在磁場，其大小和導(dǎo)線中的電流成正比，故可以利用霍爾元件測量出磁場，就可確定導(dǎo)線電流的大小。利用這一原理可以設(shè)計制成霍爾電流傳感器。若把霍爾元件置于電場強度為E、磁場強度為H的電磁場中，則在該元件中將產(chǎn)生電流I，元件上同時產(chǎn)生的霍爾電位差和電場強度E成正比，如果再測出該電磁場的磁場強度，則電磁場的功率密度瞬時值P可由確定。茂名HX6574霍爾開關(guān)廠家質(zhì)量霍爾元件盡在華芯--十六年專業(yè)做霍爾華芯專業(yè)大量提供霍爾元件批發(fā),量大采購有優(yōu)惠!</p><div

霍爾元件是由霍爾片、4根引線和殼體組成。霍爾片是一塊矩形半導(dǎo)體單晶薄片（一般為4mm×2mm×），在它的長度方向兩端面上焊有a、b兩根引線，稱為控制電流端引線，通常用紅色導(dǎo)線。其焊接處稱為控制電流極（或稱激勵電流），要求焊接處接觸電阻很小，并呈純電阻，即歐姆接觸（無PN結(jié)特性）。在薄片的另兩側(cè)端面的中間以點的形式對稱地焊有c、d兩根霍爾輸出引線，通常用綠色導(dǎo)線。其焊接處稱為霍爾電極，要求歐姆接觸，且電極寬度與基片長度之比小于，否則影響輸出。霍爾元件的殼體上用非導(dǎo)磁金屬、陶瓷或環(huán)氧樹脂封裝。目前，**常用的霍爾元件材料是鍺（Ge）、硅（Si）、銻化銦（ISb）、砷化銦（lnAs）和不同比例亞砷酸銦和磷酸銦組成的ln型固熔體等半導(dǎo)體材料。值得一提的是，20世紀80年代末出現(xiàn)了一種新型霍爾元件——超晶格結(jié)構(gòu)（砷化鋁/砷化鎵）的霍爾元件，它可以用來測10-T的微磁場。可以說，超晶格霍爾元件是霍爾元件的一個質(zhì)的飛躍。 </p><p> 霍爾開關(guān)器件 </p> <p> 按照霍爾開關(guān)的感應(yīng)方式可將它們分為：單極性霍爾開關(guān)、雙極性霍爾開關(guān)、全極性霍爾開關(guān)。 </p> <p> 單極性霍爾開關(guān)的感應(yīng)方式：磁場的一個磁極靠近它，輸出低電位電壓（低電平）或關(guān)的信號，磁場磁極離開它輸出高電位電壓（高電平）或開的信號，但要注意的是，單極性霍爾開關(guān)它會指定某磁極感應(yīng)才有效，一般是正面感應(yīng)磁場S極，反面感應(yīng)N極。 </p> <p> 雙極性霍爾開關(guān)的感應(yīng)方式：因為磁場有兩個磁極N、S（正磁或負磁），所以兩個磁極分別控制雙極性霍爾開關(guān)的開和關(guān)（高低電平），它一般具有鎖定的作用，也就是說當(dāng)磁極離開后，霍爾輸出信號不發(fā)生改變，直到另一個磁極感應(yīng)。另外，雙極性霍爾開關(guān)的初始狀態(tài)是隨機輸出，有可能是高電平，也有可能是低電平。全極性霍爾開關(guān)的感應(yīng)方式：全極性霍爾開關(guān)的感應(yīng)方式與單極性霍爾開關(guān)的感應(yīng)方式相似，區(qū)別在于，單極性霍爾開關(guān)會指定磁極，而全極性霍爾開關(guān)不會指定磁極，任何磁極靠近輸出低電平信號，離開輸出高電平信號。霍爾元件,華芯多年專業(yè)做霍爾,大品牌值得信賴,精選各類霍爾元件,好評如潮,庫存充足!霍爾元件一站搞定。</p><div
